Internally, this function calls sta_info_get_by_addrs(), what has a couple of drawbacks: 1. additional station lookup causes a performance degradation; 2. mac80211 can not properly account Ethernet encapsulated frames due to the inability to properly determine the destination (station) MAC address since ieee80211_tx_status() assumes the frame has a 802.11 header. The latter is especially destructive if we want to use hardware frames encapsulation. To fix both of these issues, replace ieee80211_tx_status() with ieee80211_tx_status_ext() call and feed it station pointer from the tx queue associated with the transmitted frame.

The firmware is able to do this operation for us, so enable encapsulation offloading for AP and Sta interface types to improve overall system performance. The driver is almost ready for encapsulation offloading support. There are only a few places where the driver assumes the frame format is IEEE 802.11 that need to be fixed. Encapsulation offloading is currently disabled by default and the driver utilizes mac80211 encapsulation support. To activate offloading, the frame_mode=2 parameter should be passed during module loading. On a QCA9563+QCA9888-based access point in bridged mode, encapsulation offloading increases TCP 16-streams DL throughput from 365 to 396 mbps (+8%) and UDP DL throughput from 436 to 483 mbps (+11%).
